Embodiment Construction

[0028] In order to better understand the present invention, the technical scheme of the present invention will be further described below in conjunction with embodiment and accompanying drawing (as Figure 1-2 shown).

[0029] An automatic background separation method based on the rotation of the captured image:

[0030] S1, collecting continuous image sequence data based on rotation shooting;

[0031] In order to obtain the continuous image sequence of the target object to be photographed, the present invention uses the idea of ​​turning table photography here, and the specific steps are as follows:

[0032] 1) Image acquisition equipment 1 such as a camera or video camera is installed on a fixed support 3 (such as a tripod or a device capable of fixing the camera), and the target object 4 to be photographed is placed on the turntable 2; the rotating photographing adopts a rotating photographing device , the rotating shooting device includes an image acquisition device 1 fo...

Abstract

The invention belongs to the technical field of digital image processing, in particular to a method for automatically separating background before image capturing base on rotation. S1, collecting continuous image sequence data based on rotating shooting; S2, preliminary marking of the foreground and background of the image according to the changed part in the adjacent image; S3, using graph theoryto segment the foreground and background of the preliminary marker accurately. The invention mainly solves the problem of separating the background before the image based on the rotary shooting, andsolves the problem of background elimination or matting in the application such as multi-angle object display based on the rotary table, three-dimensional modeling and the like. The method is simple,efficient and highly automated. Only the continuous images can be input, the background can be separated automatically, and a lot of human cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a method for automatically separating the front and background of an image captured by rotation. Background technique [0002] Image foreground and background separation is actually a binary labeling problem of images. Since the image foreground and background separation technology is aimed at any part of the image of interest, different degrees of human interaction, different prior information, and various characteristics in natural images Different assumptions and different types of constraints can make completely different separation results, so image foreground and background separation is an important and difficult problem in the fields of image understanding, pattern recognition and computer vision. At present, foreground and background separation technology has been widely used in target recognition, digital image and video production, image-ba...
